Abstract

Un turbomotore a gas da aereo è munito di un sistema di rifornimento di aria compressa generalmente usata per soddisfare esigenze specifiche o di aria di prelievo di aereo. Questo sistema di rifornimento di aria compressa comprende un compressore ausiliario, un mezzo per azionare meccanicamente il sistema da un rotore della turbina a gas e un mezzo variatore di ciclo, come un azionatore a velocità variabile, per azionare il ciclo del compressore ausiliario indipendentemente dal ciclo del compressore del turbomotore a gas di aereo. La realizzazione preferita fornisce un mezzo per prelevare aria dallo strato limite fuori dalla navicella o da un'altra parte del guscio esterno di aereo e per usarla come sorgente di aria per il compressore ausiliario. Una realizzazione contiene una turbina ad aria su un albero comune con il compressore ausiliario e un mezzo per dirigere una porzione non usata della corrente di aria dal compressore ausiliario alla turbina ausiliaria allo scopo di aiutare ad azionare il compressore ausiliario e un'altra realizzazione contiene un mezzo per dirigere aria compressa di avviamento alla turbina ad aria per un avviamento a terra e in volo del turbomotore a gas attraverso l'azionatore a velocità variabile e un collegamento meccanico al rotore del turbomotore a gas.
